I guess I was wondering if there had been studies on the effectiveness of unions and looking at how many, if not negligible, have had reported cases of corruption and / or fraud.
Like I say I do believe unions do more good for workers than bad, but I also do believe that any organisation that gets to a certain size is inevitably going to be corrupt as the people that are going to be corrupt will do what is necessary to rise to the top.
Just buy a burner. Use it once to sign up and throw it away.
